Description: The scientific goal of the 08ID-1 beamline is to operate a protein crystallography beamline suitable for studying small crystals and crystals with large unit cells. The overall design of the beamline contains white beam slits (WBS), a double crystal monochromator (DCM) with an indirectly cryo-cooled first crystal and sagittally focusing second crystal, and vertically focussing mirror (VFM). The beamline is completed with an innovative and very robust endstation with Mar300CCD X-ray detector. The beamline controls are being developed based on EPICS and are complemented with a Blu-Ice-like user interface.

The beamline is equipped with a Röntek Spectrometer System XFLASH 101A to perform X-ray spectroscopy for MAD and X-ray absorption near edge structure (XANES) on the same crystals, and the X-ray fluorescence (XRF) for metal tracing on protein derivative crystals. There are ongoing efforts to equip the beamline with a cryogenic sample changer to facilitate remote access to the facility.

Endstation(s):

• Rontek XFLASH 101A Spectrometer
• Automounter (under development)
• Oxford Instruments Cryojet
• Marmosaic CCD300
• Huber Model 410 goniometer with single phi axis

Techniques:

• Single crystal X-ray diffraction
• Multiwavelength Anomalous Dispersion (MAD)
• XANES on crystals

Optics: DCM with cryo-cooled 1^st crystal sagittally bent 2^nd crystal followed by vertically focusing mirror.
